120-degree push-on hose end in AN6 (-6), pushing straight onto socketless hose and gripping the barb without a clamp or crimped socket. AN6 is the everyday size: carburettor fuel feed, EFI returns, coolant overflow and header-tank runs, PCV and light oil plumbing on most street and club-level builds. At 120 degrees the hose turns back past square, suiting ports that face away from the run and would otherwise need an untidy loop to recover. It offers enough bore for typical fuel and coolant duty without the bulk of the larger sizes. Intended for push-on hose only, not braided hose built for a two-piece compression end.
